<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
On a graph, the solution of a system of equations is given by the intersection between the curves. In this graph, the intersection of the two curves happen close to x = -3.25, y = 2.5, hence the solution is approximated by:
D.

Answer:
30.06
Step-by-step explanation:
The question states WHAT DID THEY PAY BEFORE INSTALATION CHARGES.
So 30.06$
588.34-555.28=30.06
The most logical answer is C, if you multiply the hours by the wages and then subtract the expenses you will reach C.
Answer:
p=9h
Step-by-step explanation:
This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
<em>A = 84 mg</em>
